Page 10: Installation
MJ400306A1 Installation Installation place ① This equipment is designed for indoor use. Never install the equipment in a place where it is likely to be wetted by water or rain. The equipment may fail. Install the equipment in a place where sufficient ventilation is provided and changes in humidity are minimal. - Page 11 Due to the characteristics of the mass flow controller, if counterflow occurs, the fully opening action may occur even if controlled. The valve of Model 8700 Series Controller Type is intended for precise control and is different from valves designed for complete shutoff.
